Conte has indeed said that he wants Lukaku to be in the Napoli squad next season, but so far Lukaku hasn't confirmed that he wants to play at Napoli,so I think at this time we can't say if Conte will win, so far Roma and Milan also really want to recruit him and that should be a warning to Napoli not to think long now about buying Lukaku, because Lukaku previously played quite impressively with Roma and maybe he will also consider Roma if a permanent offer comes to him at this time.
I know very well that Antonio Conte wants him in the team, we knew everything and his request also has a logic.
What you want doesn't always come true, even De Rossi and Roma wanted Romero Lukaku for another year.
It seems that Milan also wanted the Belgian striker, but this did not materialize.
I don't know what cards Antonio Conte and Napoli played.
